Don’t you just hate beautiful floral garnishes that you’re not supposed to eat? No danger of that at the Gardner Café (Isabella Stewart Gardner Museum, 280 The Fenway, Boston), which, through April 16, is offering an “Edible Nasturtiums” menu inspired by the museum’s “Hanging Nasturtiums” garden display. The blossoms are incorporated into spring recipes from chef/owner Peter Crowley, including duck confit with nasturtium salad and citrus pound cake with nasturtium syrup. Call 617.278.5106 for reservations and information.
